OBA pressure switch wiring

I'm having a brain fart /forums/images/graemlins/yikes.gif and can't figure out how to wire up my power source to the pressure switch to the compressor. Who has already hooked up there OBA that can take a pic of the wiring of their pressure switch and label the wiring for me? I'm using a 30A relay and need the wiring from the relay to the pressure switch to the compressor.

its a double posted switch.. you can make 2 connections with it. you just need to use 2 that are connected at low pressured and unconnected at high pressure. probably a diagram that shows ya which are hooked to which.

If its one of those big Square D ones, its actually for switching power to big 240V motors, where you need to switch more than one wire.

I ran outside and checked my roommates truck.. use either the top two terminals, or the bottom two terminals in the picture. and don't bother grounding the case. Remember its setup for a/c wiring, where ground is seperate from the circuits. you don't need to ground it for ANY reason.

Lemme know if it works. We've been using his (my roommates) for the last 6 months or so, built it with 3 caddy air suspension compressors. it aint the fastest, but it beats the hell out of an ARB compressor or driving 12 miles at 12psi to a gas station.
